Just thought I would share with you what I did this spring.. I had a day out to a bonsai growing field. And in the field I found thr last 2 prunus Mume he had. To be honest.. He kept them for the flowers, and had been less then perfect in maintaining them.
I could not decide which was less ugly, so I decided to take both off his hands, to keep my options open, and allowing to perhaps sell one later on.
I trimmed them back, and left them in the field. Hoping for backbudding. Later this summer I will go there once more, and do a second trim. Hopefully, come spring, they will have lots of buds near the trunk so I can cut back to an open crown and hopefully, pleasing trunkline. I could not decide upon one in March, unfortunately.
